Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the main view of the utility model；
Fig. 3 is the draught hood of the utility model and the connection top view of slide cartridge.
In figure: 1 slag storehouse, 2 scum pipes, 21 cross bars, 22 helical-blades, 23 motors, 24 driving pulleys, 3 draught hoods, 31 may be programmed
PLC controller, 32 filter screens, 33 exhaust fans, 34 slide cartridges.
Specific embodiment
As shown in Figures 1 to 3, a kind of PLC controls power plant boiler deslagging cleaner, including slag storehouse 1 and setting in slag
The inner cavity upside of the scum pipe 2 of 1 downside of storehouse, scum pipe 2 is equipped with slag-discharging valve, is provided at the axis of scum pipe 2 and stretches downwards
Bull stick out, and the upper end of bull stick is rotatably connected to upper and lower two cross bars 21 being fixed on scum pipe 2.
The helical-blade 22 extended downwardly being against on 2 inner wall of scum pipe is provided on bull stick, and activity installation on scum pipe 2
